Theother day I did find a NOS water pump dirt cheap GM/Delco 231886 it is just over 5 1/2" and has a large 5" impeller.
From what I found out so is this for the old Olds 350 diesel but should fit my -73 455.

As the 350 diesel has a lower rpm band just as we have in the GMC with a larger impeller this could be (In my head ) a perfect fit or am I on the wrong track here ?


1973 23' # 1848 Sky Blue Glacier called Baby Blue and a 1973 26'-3 # 1460 Parrot green Seqouia Known as the Big Green, And sold my 1973 26'-2 # 581 White Canyon lands under the name Dobbelt trøbbel in Norway
